The Bose QuietComfort Ultra Earbuds (2nd Gen) are a significant upgrade from the previous generation to significantly enhance the user experience. They add essential features that were previously missing from the 1st-gen product, while maintaining the same price tag. The Bose QC Ultrasports are designed for outdoor use and provide all-day comfort in a familiar style. They also feature a guard to manage earwax buildup, which Bose claims helps make it easier to capture and remove ear wax after prolonged use. The charging case is bulky and awkward-looking, but it's built to last. Despite the larger earbuds' size, Bose's reviewer found no accidental earbud drops on his unit. The QC Ultra Earbs 2 produce pleasing audio with boosted bass and highs and support AAC, SBC, and aptX Adaptive Bluetooth codecs, as well as Google Fast Pair and Microsoft Swift Pair for quick device-to-device connections.
